Chef 12 and Chef Development Kit 1
EOL Information and Resources

In April 2018, Chef will release new versions of the Chef client (Chef 14) and Chef Development Kit (ChefDK 3). At the same time, support for Chef 12 client and ChefDK 1 will be discontinued. This page has been created to provide an overview of the changes, and a set of resources to help you and your organization plan and deliver a seamless migration. This page will be frequently updated with the latest information about the migration and new and updated how-to resources for the migration.

Chef 12 & ChefDK 1 End of Support FAQ

Chef Client 13.0 was released April 2017. We have made a huge number of improvements since then, removing obsolete code and changing behaviors to ensure safety, correctness, and performance of your cookbook code while introducing many new resources and improved functionality.

Some of the resources under development include:

docker_container, docker_registry, docker_exec, and docker_network

ohai_hint and chef_handler, for easier cookbook development

dmg_package, homebrew_cask, and homebrew_tap for macOS support

windows_font, powershell_module, and a few other Windows resources

So that you can plan for updates we’ve introduced a regular release cadence, with backwards compatible releases of Chef Client each month, and a yearly “major” release. A major revision honors our Semantic Versioning contract.

Chef 11 and 10 have entered “end of life” and are no longer supported.

Chef Server 12 is and will remain the current version of Chef Server. Chef Server 12 is fully forwards and backwards compatible, and will continue to support new releases of the Chef client. We always recommend you upgrade to the latest version of the Chef server.

Chef 12 & ChefDK 1 – End of Life – April 30, 2018

In the sense that they will still continue to function in existing environments, yes. However, they will no longer be supported by Chef and we strongly encourage upgrading to the most recent versions in order to take advantage of the many new features and functionality that are available.

Chef guarantees support for a minimum of two years from the initial major version release date for applications included in the Chef Automate subscription. Extended support may be offered based on market need, at Chef’s discretion.

If you are currently on unsupported versions, as a premium support customer, we will work with you to upgrade to our latest version. As of April 30, 2018, Chef 12 will no longer be a supported version.

Premium support customers should contact their Customer Success Manager or the Customer Success team (success@chef.io) for guidance.

We also have professional services offerings that are designed to support everything from architectural review, upgrade planning and execution. For more information on these offerings, please contact sales@chef.io
